Thanks very much for the quick reply and suggestion, but it didn’t make a difference. I think I’d already tried that.

It seems (after a whole evening’s experimentation and help docs) that there’s no way to process a recorded audio file with the iOS version of Bias FX or AMP. I guess they’re only set up to work on a live signal, either by mic or adapter, such as IRIG.

So, what’s happening is that the BIAS app isn’t taking a signal back from Auria to process, then return to Auria, post processed. It only acts as an insert before Auria to allow processing of the incoming live signal, to be recorded by Auria.

On your list of FX you will see 2 Bias Amp. Only one of these two will work. This is a naming error from Positive Grid that has been around since I beta tested this app. So the one you loaded is the one thats not working so load the other one. You will know because the one that works will not turn on the record light. The one that turns the red record light on when loaded is the wrong one. I just tested and its working fine and as it should. It will apply effects to any file already recorded. I tested with Bias Amp. Cheers good luck.

That is right. Every Positive Grid app has 2 names of the same app. I reported this error to them so many times I gave up and just worked around it. Why they can't fix this I will never know. However this Positive Grid naming error is only in Auria and no other daw. This is why they haven't fixed it. There is something about the way Auria handles their apps that creates this problem. Good luck.
